Teplice lies between Prague and Dresden in a mountain area called Krušné hory (Iron Mountains). In the year 762 hot springs were found there. The waters from these springs helped people who were ill to get better so it became a spa town.

Since 1990 many buildings have been restored. The Krušnohorské divadlo (Krušnohorské theatre) is now being refurbished. The North Bohemia Philharmonic Orchestra give concerts there in the open air. There is a museum and many restaurants, winebars and cafés. In the winter the mountain slopes are good for skiing.
